Description

Rubber tree combined budding knife

technical field

The utility model belongs to the technical field of agriculture, and relates to a rubber tree seedling grafting tool, in particular to a rubber tree combined bud grafting knife composed of multiple blades.

Background technique

Bud grafting is the main way of propagation of rubber tree clonal seedlings. The bud grafting method of rubber tree grafting technology is to graft dormant buds such as leaf buds, scale buds, and dense node buds of excellent asexual (or sexual) lines of rubber trees as scions to seed seedlings and rootstocks. A method of asexual reproduction. At present, the tools used for budding of rubber trees are mainly single-knife budding knives. When opening the bud interface, use the bud knives to cut one knife from left to right, from bottom to top. Tight fit, the bud piece is generally trimmed according to the size of the rootstock. Before the bud piece is inserted, it needs to be trimmed and cut many times. This requires high budding skills for the operator. At the same time, due to so many cuts, not only the work efficiency is low, but also It also affects the survival rate because of the slow operation speed.

Utility model content

The purpose of this utility model is to provide a rubber tree combined budding knife for the deficiencies of the prior art, combining multiple groups of blades can effectively control the width of the bud interface and bud slices, reduce the number of cutting times, and improve the survival rate of bud grafting .

The technical scheme adopted in the utility model:

A rubber tree combined budding knife, including a scabbard, a movable shaft at one end of the scabbard is connected to a cutting knife, so that the cutting knife can be folded into the scabbard; the other end of the scabbard is flexibly connected with two pieces of the scabbard to expand outwards through an adjustment mechanism The other ends of the two oblique blades are fixedly connected to the parallel straight blades through the connecting block, and the distance between the oblique blades and the straight blades can be adjusted through the adjustment mechanism to meet the appropriate operating requirements. Straight blades cut two vertical marks simultaneously on the rootstock.

Described adjusting mechanism is made of adjusting knob, bolt and spring, and wherein bolt is arranged on the end of scabbard, and the middle part of adjusting knob is provided with spring, and adjusting knob passes through bolt, inclined blade, spring, and two ends cooperate with bolt, and spring and The adjustment knob is sliding fit, and the two oblique blades are respectively arranged at the two ends of the spring.

The utility model has a simple structure, and multiple groups of blades are combined to effectively control the width of the bud interface and the bud slices, increase the speed of bud grafting, reduce the number of cuts, and avoid the occurrence of buds caused by frequent handling and placement of bud slices by a single bud grafting knife. It has the characteristics of simple production, low cost, easy to carry, easy disassembly and assembly of blades, etc., making mass production of rubber budding seedlings possible.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and embodiments, but not as a limitation of the utility model.

In the structure shown in the figure, the utility model includes a scabbard 5, a movable shaft at one end of the scabbard is connected to a cutting knife 6, and the other end of the scabbard is flexibly connected to two oblique blades that are inclined outwards and become enlarged through an adjustment mechanism. 3. The adjustment mechanism is composed of an adjustment knob 4, a bolt 8 and a spring 7, wherein the bolt 8 is arranged at the end of the scabbard 5, the middle part of the adjustment knob 4 is provided with a spring 7, and the adjustment knob 4 passes through the bolt 8, the inclined blade 3, the spring 7. The two ends are matched with the bolt 8, the spring 7 is slidingly matched with the adjustment knob 4, and the two oblique blades are respectively arranged at the two ends of the spring 7; the other ends of the two oblique blades are fixedly connected to each other through the connecting block 2. Straight blade1. Rotating the adjustment knob 4 can adjust the distance between the oblique blades 3 and between the straight blades 1 to make it reach suitable operation requirements, and utilize the straight blade 1 to simultaneously cut two vertical marks on the stock.

During budding, open cutting knife 6, oblique blade 3, rotate adjustment knob 4 to adjust the distance between oblique blade 3 and straight blade 1 to make it reach suitable operation requirements, then use straight blade 1 on the rootstock from bottom to bottom Cut one knife on each top, complete at one time, the upper and lower parts are parallel to each other, use the cutting knife 6 to cut across the top one knife, and use the tip of the knife to pick up the cortex from the knife receiving place, peel from top to bottom to the knife starting place, at the bottom of the cortex 1 ~ 2cm Excise the cortex at the place, after the bud slices that are cut off are peeled off the wood chips, use the oblique blade 3 and the cutting knife 6 to repair and cut the both sides and two ends of the bud slices respectively, and finally paste the bud slices into a suitable size rectangular bud slice to the rootstock. On the xylem, quickly bind the bud interface with a plastic film.
